51.   Misfolded proteins are also behind the spongiform encephalopathies, diseases that involve strange, spongelike holes in certain parts of the brain.

52.   Mice lacking the gene appear healthy, suggesting that the normal prion protein is not an essential protein in mice.

53.   More important from a health standpoint, however, may be the fact that the protein in nuts is especially rich in an amino acid called arginine.

54.   Once a protein is folded and ready to go to work, the chaperone pops off and finds another unfolded protein to protect, Cohen said.

55.   One possibility, Roberto said, is to insert a mussel gene into a plant through genetic engineering so that the supersticky proteins can be grown as a crop.

56.   Other companies, such as Cytogen and Oxford Glycosciences, are pursuing proteomics, determining which proteins are present in particular cells.

57.   Protein is widely available in breads, cereals, nuts, peanut butter, tofu, milk and low-fat cheese.

58.   Prusiner said that the infectious prion protein is just like the normal one except that it is folded into a different shape.

59.   Protein can be a concern too.

60.   Proteins can be fragile.
